Zhmentor Patented Sept. 16, 1941 UNITED STATES PATENT OFFICE SANITARY VALVE Niles Atterbury, Pittsburgh, Pa. Application July 25, 1939, Serial No. 286,317 1 Claim. (Cl. 251-497) My invention relates to a valve, and while primarily designed and intended for use in connection with dairy equipment or any other installations requiring sanitary fittings, it will be apparent that the valve may be employed for any other purposes wherein it is found to be applicable.

Important objects and advantages of the invention are to provide a valve of the character described, which is dually protected to render same leak proof and to prevent seepage, which embodies a valve plug having a passage opening conforming in size, contour and area to the passage of the associated valve body, whereby the product is allowed to flow straight through the valve structure without undue friction, which may be readily taken apart for cleaning purposes and conveniently reassembled, which is simple in its construction and arrangement having but few parts, which requires no packing, which is durable and efiicient in its use, attractive in appearance, and comparatively economical in its manufacture, installation, and maintenance.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, but it is to be understood that changes in the form, proportions and details of construction may be resorted to that come within the scope of the claim hereunto appended.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a longitudinal, vertical, cross sectional view of a valve constructed in accordance with the invention.

Figure 2 is a side elevational view of the valve plug taken at right angles relatively to the view thereof shown in Figure 1.

Referring in detail to the drawing I denotes the entire valve body, which is preferably positioned horizontally, as illustrated, when installed. It is however, obvious that the valve body may be disposed in any other position to meet re-. quirements found in practice without departing from the spirit of" the invention.

The valve body I is generally cylindrical and elongated and is provided with a correspondingly-shaped passage 2, which latter has open ends and extends throughout the length of the valve body.

The valve body I is formed to provide a plug barrel 3, which extends vertically and at right angles to the longitudinal disposition of the valve body, intermediate of the ends of the latter. The ends of the valve body have conventional formations adapting same for connection in the installation of the valve structure and associated conduits.

The top of the plug barrel 3 is formed with a large top opening 4, which is surrounded by a collar flange 5. The latter projects upwardly from the valve body I and has a tapered inner periphery increasing the diameter of the latter from the lower to the upper end thereof. The bottom 1 of the plug barrel extends below the valve body and has a rounded inner peripheral edge.

A seating sleeve 8 is formed integral with and depends from the diametric center of the barrel bottom 1. The seating sleeve has a tapered inner periphery 9 increasing the diameter of the latter from the lower to the upper end thereof.

A cylindrical valve plug I0 is vertically and revolubly mounted in the bore 6 of the plug barrel 3 through the top opening 4, and extends through the valve passage 2. The periphery of the valve plug is frictionally seated against the bore wall of the plug barrel, and the adjustment of the valve plug in the latter will open or close the valve in the manner to be described.

The peripheral bottom edge of the valve plug l0 being rounded, extends into the correspondingly rounded barrel bottom. The latter dips toward the passage of the seating neck 8 so that when cleaning the valve structure, no liquid will deposit on the barrel bottom, but will drain therefrom by gravity.

A tapered seating stem I l depends from the diametric center of the bottom of the valve plug l0, and is seated against the correspondingly tapered inner periphery of the seating neck. The seating stem is formed with an annular groove l2 for the reception of a suitable lubricant to facilitate the adjustment of the valve plug in the valve body.

The seating stem carries a reduced connecting shank l3, which projects beyond the free end of the seating neck 8 when the valve plug [0 is assembled in the valve body I. An operating crossbar I6 and a connecting hub I5 are removably attached to the connecting shank by the engagement of said crossbar in apertures l1 and I8 respectively provided in said shank and connecting hub. The crossbar is slightly tapered throughout its length, and when same is driven to place through the apertures l1 and I8, the connecting through the passage'in the j of packing in any form.

hub will be forced against the free end of the seating neck and thereby draw and properly seat the seating stem in the seating neck, in the man- V shank.

The valve plug -H) is provided with a passage opening" H), which conforms in size, contour and Y area to the passage 2 in the valve body I. The

passage opening I9 extends parallel to'the cross bar I 6, so that when the latter is manipulated to adjust the valve to the open position, as shown in Figure 1, the passage opening I9 is in exact registration with the body passage 2, thereby providing an unimpeded passage throughout the valve structure. q To close the valve, the valve plug is simply adjusted to position the; passage opening I-9 therein at right angles to the body passage 2 in the manner of'an ordinary plug or cook type of valve. Acover 20, having a tapered peripheralwall, engaged in the collar flange 5 for closing the top opening 4, when the valve plug H! is assembled in the valve barrel 3, for preventing possible seepage of fluid through said opening '4. The cover 20 is removably secured in position by the engagement of a locking ring ,which latter is threadedly engaged on the collar flange 5. The tapered seated engagement of the seating stem! I in" the seating sleeve "8 will 4 prevent leakage latter without the use To take the valve apart forcleaning or any other purposes, it is only necessary to remove the locking collar I I-from 'thecollar flange 5, and to remove the crossbar l6 and connecting hub "I5 fromg'the shaft l3. By a blow on the latter, the

cover 29 may be driven from its engagement in the collar flange 5, after which the valve plug I0 may readily be lifted from the plug barrel.

The present invention provides an economically constructed and highly efficient device of its kind, which may readily be adjusted Without necessitating the release or reengagement of any of the parts of the valve structure, as is not infrequently required in' the operation of analogous sanitary valves. r

What I claim is: i i In a valve of the character, described, the combination of an elongated horizontally disposed valve body provided with a passage extending throughout the length thereof, said body being formed with a plug barrel extending vertically through said passage intermediate of the ends of the'latter, said barrel provided with a dipped bottom having arounded peripheral edge, said barrel having an open top surrounded with a collar flange; a cylindrical mounted'in said barrel an'd'having a passage opening commensurate to the transverse area of said passage and beingialigned with the latter when in the open position, the lower peripheral edge of said plug being rounded and seated in' the rounded peripheral edge of said bottom, detachable means engaged on said collar for closing said open top of said barrel, said bottom formed With a depending seating s'leevehaving a tapered inner periphery, a tapered seating stem carried by said plugand engaging in said sleeve," said stem carrying a connecting shankprojeo'ting beyond the lower end of saidsleeve, a hub mounted on the projectingend of said shank'and a'tapered cross bar longitudinally adjustable in an aperture provided-in said shank and in'sa'id hub for forcibly seating said stem in said sleeve.
